Summary A relatively warm and humid air mass is now in place over the San Joaquin Valley. Temperatures will be sub 90 at most locations this afternoon. However, dew points will hang up there in the upper 60s, meaning temperatures may warm into the upper 80s but with a heat index making it feel like temperatures are well into the 90s.
We’re tracking two main features this morning. The first is an upper low over northern California. The second is a mammoth high pressure system centered over Missouri which extends westward into the Desert Southwest and the Rocky Mountain region. Central California will enjoy a dry southwesterly flow, maintaining mostly clear skies with a warming trend. Friday and Saturday will be the warmest in the series as a new low pressure system sets up shop off the Oregon/northern California coast this weekend. It will finally move inland Tuesday. A minor cooling trend will commence Monday with a warming trend later next week.
Through this entire period the monsoon will continue to flow from old Mexico into the Desert Southwest but too far to the east to affect central California.
Forecast Mostly clear skies through Sunday. Mostly clear Sunday night through Tuesday.

Two Week Outlook: August 29 through September 4 This model shows highest pressure over the middle of the country with a weak trough of low pressure off the Pacific coast. This will result in generally average temperatures with little risk of precipitation.
August: This model indicates temperatures over the next 30 days will be near to slightly above seasonal averages. Dry weather will continue, although we will have to keep a watchful eye to the south for possible tropical activity.
August, September, October: This model shows above average temperatures for much of the west, particularly the Desert Southwest. It also points to below average precipitation over the Desert Southwest, possibly meaning a less active monsoon season. The chance of precipitation for central California appears to be near average.
Wind Discussion: Winds today will be variable to 15 mph. Stronger gusts are possible in the vicinity of showers or thunderstorms. Winds tonight through Thursday will be generally at or less than 7mph nights and mornings with periods of near calm conditions. Winds during the afternoons will generally be out of the west to northwest at 8 to 15 mph through Friday.
Rain Discussion: Expect dry conditions.
Mid afternoon dew points: Mid to upper 60s. Kern: Mid to upper 60s.
